I'm not normally one to shill products (anyone want to buy Amway products?--just kidding) but this seems like a good deal. Chase Freedom Unlimited is offering $200 for free if you spend $500 in three months. And 5% back on groceries for the first year. And always 3% at restaurants and drug stores. No annual fee. This assumes you don't already have said card. But you can have other Chase cards and still qualify.
Also, I can supply a referral link. If you do that then I would get $100 which I would donate entirely to the MoT website. PM me if you want the referral link (I can only refer four more times) otherwise you can find the offer here.
